Above-Grade Waterproofing for Allentown Offices, Hospitals, Hotels & Apartments
Commercial Waterproofing Contractors in Allentown, PA
Allentown buildings get water from every season. Snow piles on ledges and parapets in winter and melts into open joints and cracked mortar, then refreezes and widens the gap. Nor’easters soak facades for days, summer thunderstorms drop heavy rain in minutes, and the remnants of tropical storms have flooded parts of the Lehigh Valley. Humid summers then age the sealants and coatings meant to keep it all out.
Presto Restoration has more than 25 years of experience in above-grade commercial waterproofing. In Allentown, our crews reseal expansion joints and window perimeters, coat walls and parapets with silicone and elastomeric systems and protect masonry with breathable repellents on office buildings, hotels, hospitals, college buildings and apartment communities. We also make our own restoration products, including Glass Defender for glass and Leach Stop for precast concrete.
OUR COMMERCIAL WATERPROOFING SERVICES IN ALLENTOWN
We handle every kind of above-grade waterproofing on Allentown commercial buildings, from a single leaking window to a complete envelope program.
Core Waterproofing Services
Expansion and control joints let buildings move through cold winters and hot summers. As the sealant ages, it tears and lets meltwater and rain into the structure. We remove failed joint materials, rebuild damaged edges and install sealants or preformed systems sized for the movement, and we rout and seal active cracks.
Window perimeters cause many leaks in Allentown offices and apartments. Freeze-thaw and wind-driven rain crack the sealant or pull it from the frame. We replace perimeter seals, reseal mullion joints and fix gaskets, and stained glass can be restored and protected with Glass Defender.
Ledges, parapets, canopies and balconies collect snow and rain, and freeze-thaw cracks them open. We apply high-solids silicone coatings that tolerate ponding water, stay flexible in the cold and resist UV.
Older Allentown office buildings often rely on dry glazing gaskets that shrink with age, letting rain into the frame. Wet glazing adds a continuous silicone seal between glass and frame, stopping leaks without replacing the windows.
Concrete, stucco and EIFS walls crack after years of freeze-thaw, and every crack lets water in. Elastomeric coatings span the cracks and flex as the wall moves, applied at full thickness after larger cracks are repaired.
Brick, block, stone and precast absorb water that freezes and breaks them apart. Breathable water repellents cut that absorption while letting moisture escape, applied after cracks and joints are repaired.
Specialized Restoration-Waterproofing
Beyond sealing, Presto restores the glass, metal, stone and concrete beneath, using products we make in-house, so cleaning, repair and waterproofing happen in one project.
Precast panels leach natural salts that leave white streaks as water dries, and road salt makes it worse. Leach Stop is our treatment designed to reduce this. We clean deposits, treat the panels and reseal the joints.
Metal panels, Alucobond cladding, coping and curtain wall frames rely on sealant at every joint, and metal moves sharply between seasons. We replace failed sealants with products made for metal movement and reseal every lap and fastener.

Allentown Commercial Waterproofing FAQs
How often should sealants be replaced on an Allentown building?
Most commercial sealants in the Lehigh Valley last about 10 to 15 years. Joints on sunny or storm-facing elevations usually fail first, so a yearly look is worthwhile.
What is the difference between waterproofing and water damage repair?
Waterproofing stops water at the exterior. Water damage repair fixes what water has already harmed inside. We focus on stopping the water so interior repairs do not have to be repeated.
Can waterproofing be done while the building is occupied?
Yes. Almost all of our work is done from the outside, and we schedule around office hours, patients and residents.
What is the difference between elastomeric coatings and water repellents?
Elastomeric coatings form a flexible film that bridges cracks and changes the wall’s look. Water repellents soak into masonry and block water invisibly. Historic brick usually needs a breathable repellent.
How do I know if waterproofing can wait another year?
Leaks during storms or snowmelt, damp walls or split caulking are reasons to act now. If sealants are still flexible and nothing is leaking, planned replacement over the next few seasons is usually fine.
Can waterproofing work be done in an Allentown winter?
Most sealants and coatings need about 40 degrees Fahrenheit or warmer to cure, so the main season runs from spring through fall, with emergency repairs possible in winter.
